The M865 TPCSDS-T Kinetic Energy (KE) training round, in service with the United States Army’s main battle tank fleet, utilizes a unique cone stabilizer to limit the safety fan required for tank gunnery. With its matched exterior ballistics, the M865 provides a realistic training device displaying the accuracy and time-of-flight of the service round. The cone stabilizer provides a safety feature limiting the overall flight range to under 8 km, reducing the requirement for extreme range safety fans. The M865 utilizing the same combustible cartridge case as the service round, and designed to resemble the 120mm M829 Armor-Piercing, Fin-Stabilized, Discarding-Sabot Tracer (APFSDS-T) rounds in operational performance.
The main armament of the M1A1 and M1A2 is the M256A1 120 mm smoothbore gun, designed by Rheinmetall AG of Germany, manufactured under license in the U.S. by Watervliet Arsenal, New York. The M256A1 is a variant of the Rheinmetall 120 mm L/44 gun carried on the German Leopard 2 on all variants up to the Leopard 2A5. Leopard 2A6 replaced the L/44 barrel with a longer L/55. Due to the increased calibre, only 40 or 42 rounds are able to be stored depending on if the tank is an A1 or A2 model. The primary APFSDS round of the Abrams is the depleted uranium M829 round, of which four variants have been designed. M829A1, known as the “Silver Bullet”, saw widespread service in the Gulf War,
